Research

research_universe

The research universe: one row per ticker+ISIN pair of listed shares and units traded on the B3 cash market since 2019-01-02 (the start of the tape), ordered by ticker then ISIN. Membership is the ISIN's own instrument code (ACN shares; CDA and UNT units, whose ticker must end in 11); subscription receipts, BDRs, funds and indices are outside it. The ISIN is the identity: a rename is a NEW row and nothing links it to the old one, and two tickers can share an ISIN (NEOE3 and NEOE3B). first_observed / last_observed / n_sessions are facts about SILO's tape, not listing or delisting dates (FCA dates are not historical); n_sessions far below the calendar span is a gap (NATU3). cnpj comes from CVM's published FCA ticker map and cnpj_basis says how: fca_ticker (that exact ticker), fca_issuer_stem (the ticker's 4-letter stem, when exactly one CNPJ holds an FCA ticker with it: an inference), or NULL (no link; cnpj and setor_current are NULL). setor_current is CVM's cadastro setor as of today, never the setor on a past date. Read the universe at a date T as the rows with first_observed <= T <= last_observed; a pair inside a gap still matches. Served from a view rebuilt daily: last_observed lags the tape by up to a day, built_at says when. Not trimmed: more than 1000 rows RAISES 22023. **Row cap.** A window producing more than 1000 rows raises SQLSTATE `22023` naming this function. Nothing is trimmed to fit — PostgREST would silently cut the response at 1000 and a cut-short series is indistinguishable from one that simply ends. This function does not page — narrow the window instead.

Authorizations

apikey

string

header

required

The publishable key (sb_publishable_…), on every request. It is NOT a JWT — sending it as Authorization: Bearer is rejected as an invalid JWT. It identifies the project, not you, and maps to the Postgres anon role.

Body

application/json

This function takes no arguments; send {}.

Response

The result set, ticker, then ISIN. An unknown id is an empty array, not a 404 and never a guessed value.
